Multiple moles changing at once?

Over the past 3 or 4 months, I noticed a mole start changing, size and color. Then I notice 2 more. They have been continuing to do so since I noticed them.

One is on my upper arm. It was a mole that was colored brown, but now the flesh colored skin around it is raising up.Another is on my thigh, which is doing the same thing, but also has one little spot darker than the rest.One is on my back, and it is dark brown, and almost feels like a scab, which is what I thought it was at first.

Since there is more than 1 changing at once, should I not be so worried, or be more worried?
